The Bank is in the Royal Waterways, inside a room you reach through a side passage

The Bank in Hollow Knight is a small structure located in the Royal Waterways, one of the game's main areas. To reach it, you need to enter the Royal Waterways from Kingdom's Edge or from the Ancient Basin, then navigate to the eastern side of the map. Look for a room with a large circular door—this is the Bank entrance. The room itself is small and contains a single NPC called Unbank, who runs the operation.

The Bank is not a required location to progress through the game, but it serves a specific function that becomes useful as you collect more currency. Unlike a real bank, Hollow Knight's Bank does not hold your money for safekeeping in the traditional sense. Instead, it stores Mask Shards and Vessel Fragments—items that increase your health and magic capacity—in exchange for Geo, the game's currency.

Key Takeaways

  • The Bank is located in the Royal Waterways on the eastern side of the map, accessible through a large circular door.
  • Unbank, the NPC who runs the Bank, will trade your Geo for Mask Shards and Vessel Fragments that permanently increase your stats.
  • You can deposit Geo into the Bank at any time, and Unbank will hold it until you have enough to purchase the items you want.
  • The Bank is optional—you can complete the game without using it, but it provides a way to spend excess currency on permanent upgrades.
  • If you die after depositing Geo, the money remains safe in the Bank and does not drop as it would in your inventory.

How the Bank transaction works

When you speak to Unbank, you can deposit Geo into the Bank. The amount you deposit is stored there permanently until you choose to withdraw it or spend it. Unbank offers two types of purchases: Mask Shards for 500 Geo each and Vessel Fragments for 900 Geo each. Each Mask Shard increases your maximum health by half a mask, and each Vessel Fragment increases your magic capacity by one unit.

The key advantage of the Bank is that deposited Geo is protected. In Hollow Knight, when you die, you drop all the Geo you were carrying and must return to that spot to reclaim it. If you die before retrieving it, that Geo is lost. Money stored in the Bank, however, remains there even if you die repeatedly. This makes the Bank useful for players who want to save up for expensive upgrades without the risk of losing their currency to death.

You can withdraw your Geo at any time by speaking to Unbank again. There is no penalty for withdrawing, and no time limit on how long money can sit in the Bank. This flexibility means you can deposit Geo whenever your inventory feels full or whenever you want to find funds for a future purchase.

Why you might use the Bank instead of other upgrade sources

Hollow Knight offers several ways to increase your health and magic capacity. You can find Mask Shards and Vessel Fragments scattered throughout the world as hidden items, and you can also purchase them from other NPCs. The Bank is one option among several, not the only path to these upgrades. Some players never use the Bank and instead hunt for the items hidden in the environment or trade with other vendors.

The Bank becomes most useful if you have accumulated a large amount of Geo and want a straightforward way to convert it into permanent stat increases. If you are a player who explores thoroughly and finds most hidden items naturally, you may not need the Bank at all. If you prefer to farm Geo by defeating enemies and want a safe place to store it, the Bank fills that role.

The location on the map and how to navigate there

The Royal Waterways is accessed from the Kingdom's Edge to the west or from the Ancient Basin to the east. Once inside the Royal Waterways, head toward the eastern portion of the area. The Bank room has a distinctive large circular door that stands out from other doorways in the game. The room is relatively small and contains only Unbank and the Bank's interior.

If you are having trouble locating the Royal Waterways itself, note that it is one of the larger interconnected areas in the game and connects to multiple regions. You will need to have unlocked access to at least one of the connecting areas to reach it. Once you are in the Royal Waterways, the Bank's circular door is one of the more visually distinctive features, so it should stand out as you explore.

What happens if you never visit the Bank

The Bank is entirely optional. You can complete Hollow Knight without ever depositing Geo there or purchasing anything from Unbank. Many players finish the game without using the Bank at all. The upgrades it offers—Mask Shards and Vessel Fragments—can be obtained through other means, such as finding them hidden in the world or purchasing them from other NPCs.

The only real consequence of not using the Bank is that you lose the protection it offers for your Geo. If you carry large amounts of currency and die frequently, you may lose Geo that you could have safely stored. For players who are careful with their resources or who do not accumulate large sums of Geo, this is not a significant concern.

Frequently Asked Questions

Do I need to visit the Bank to beat Hollow Knight?

No. The Bank is optional. You can complete the entire game without using it. The upgrades it sells are available through other methods, and the game does not require you to purchase anything from Unbank to progress.

What is the difference between depositing Geo and just carrying it?

Deposited Geo is safe if you die. Geo you carry drops when you die and can be lost if you do not return to retrieve it before dying again. Banked Geo stays in the Bank no matter how many times you die.

Can I get Mask Shards and Vessel Fragments without using the Bank?

Yes. These items are hidden throughout the game world and can also be purchased from other NPCs. The Bank is one option, but not the only way to obtain them.

Is there a limit to how much Geo I can deposit in the Bank?

The game does not specify a limit. In practice, you can deposit as much Geo as you accumulate. There is no penalty for storing large amounts.

What happens to my banked Geo if I start a new game?

Each playthrough is separate. If you start a new game, your Bank balance from the previous playthrough does not carry over. You begin with zero Geo in the Bank on a new save file.
